You can use this to link with nginx+lua/openresty/whatever to get a Q-powered web service that can do more than a few thousand connections per second.
Cool stuff! I can see a single machine running this being loads faster than a whole elaborate cluster of php/perl/python/node servers even with some caching.
Could this also work with just the integrated web server in q? I never tried it, but I wonder why lua is involved? Is it supposed to run parts of the logic in lua? Or does just using nginx as a reverse proxy not work well?
